250 Roubles Frigate Pallada / P.S. Nakhimov

The Pallada was a Russian 52-gun frigate that departed Kronstadt in 1852 under Captain Ivan Unkovksy, carrying Vice-Admiral Yevfimiy Putyatin on a diplomatic mission to Japan — one of the first serious Russian attempts to open formal relations with the Tokugawa shogunate. Pavel Nakhimov served as a young officer aboard earlier in his career before distinguishing himself at Sinop in 1853 and dying at the siege of Sevastopol in 1855. The frigate itself never made it home, scuttled in 1856 in the Konstantinovskaya Bay to block a British naval advance.
